Understanding the Logic Behind 7 by 7 Magic Squares

The 7 by 7 magic square is a grid of numbers arranged in a way that the sum of each row, column, and diagonal is the same. It is a mathematical curiosity that has fascinated people for centuries. A magic square is said to be of order 7 if it has 7 rows and 7 columns. The numbers used in the square range from 1 to 49, with each number appearing exactly once. The magic constant, which is the sum that each row, column, and diagonal should add up to, is 175. Creating a 7 by 7 magic square is a complex task, requiring careful arrangement of the numbers.

Abbott's has the change purse which goes with the parasol idea although I'm not a big fan of any change bag.

Do to the design of the umbrella, you will not be able to do the reverse, even if you wanted to, as it will not fit back in the tube with the silks dangling.

Creating a 7 by 7 magic square is a complex task, requiring careful arrangement of the numbers. There is a specific algorithm that can be followed to generate a magic square of order 7, but it involves a lot of calculations and iterations. It is a challenging puzzle that can be both frustrating and rewarding to solve.

I just noticed Hocus Pocus has this product on sale at quite a discount.

Does anyone know anything about Mutilated Parasol by Black Magic Company?

Is this a good version? Pros or cons?

Thanks in advance.

Bill, I do not have this, but from the description it is a one way mutilated parasol (really an umbrella), meaning it only transposes to the mutilated state, and not back.

They do not show the tube, and that is an important consideration. If it is a solid tube, that you cannot show empty and free of trickery, then you loose some of the mystery. It is most likely a tube, because of the size of the umbrella as well. Newspaper would not cover something that large.

It is big, which means additional luggage and trips to the car or van.

The bag is designed like the old bag to foulard so the bag changes into the umbrella cover. A nice touch.

This is the nice feature of the Abbott's design. Edward O. Drane company in Chicago, use to supply a less costly version of the Abbott model, but the company is long since closed. It did not have any silk parasol cover, but worked with the same principles.

There are a reason, more then money, to buy the Abbott's Mutilated Parasol. It is superior in many ways, and they can/will make an additional bag to parasol cover for an additional charge of course.

I purchased that lost version they sold from Italy, and it was similar to this model you are requesting information on, I think they called it the Dante Mutilated Parasol. I never used it because of the size and the one way feature, and I had a time trying to find something big enough to wrap it in. It did not come with a bag of any kind. I sold it here on the Café at a huge loss.

I would advise against purchasing this current offering. Just my opinion.

Thanks Bill, I think you're right on target with that analysis.

What I don't like about Abbott's is the tie-dye look. It makes more magical sense to me the way Black Magic has 16 panels on the umbrella that match the silks.

I think the bag to foulard is nice, I'd like to see how the Black Magic one looks, but usually they are pretty. This transformation is also one way like the parasol.

Abbott's has the change purse which goes with the parasol idea although I'm not a big fan of any change bag.

Here is another mutilated parasol effect:

This is pretty cool, but unfortunately uses another tie-dye parasol. He has kind of dispensed with the change bag altogether, which puts a lot of heat on the tube.

Can anyone else find a good mutilated parasol?

Bill, I have did research on the ones available on the market, and their are none better then Abbott's. I guess if you call Greg Bordner the owner and discuss your ideas, he would consider makeing a special parasol for you. I am sure you should get a quote from them first.

Owen's Magic makes one, and is so expensive, the price list says, Price on Application only.

Harries is a chrome metal tube, you have to screw the parasol into the tube to get a release for the ribs. The parasol is tiny as well.

The India models are all junk and not even a Mutilated Parasol effect.

Mr. Jupiter's is not an actualy a Mutilated Parsol effect as well.

Of course it ia a big world, so maybe there is one someplace.

Does anyone know about this one:

The 7 by 7 magic square has many interesting properties. For example, if you take any four numbers in the square that form a rectangle, the sum of those numbers will always be the same as the sum of the numbers in the opposite rectangle. Additionally, the square has rotational symmetry, meaning that it can be rotated by 90, 180, or 270 degrees and still maintain the same magic properties. While the 7 by 7 magic square is not as well-known as some of its smaller counterparts, it is still a fascinating mathematical concept. It demonstrates the intricate patterns and relationships that can exist within numbers. The challenge of creating and understanding these magic squares continues to captivate mathematicians and puzzle enthusiasts alike..
