Some minor touches

I sorted the Topics, removed "Topic:" from each of the subdivisions' names, created a new Elementary Mathematics division to help reduce clutter, and fixed a couple other minor details. MichaelShoemaker 01:12, 3 February 2009 (UTC)

Most-perfect magic square

most-perfect magic square from the Parshvanath Jain temple in Khajuraho

earlier contribution Only Three Squares,
Only One Pattern

Dear friends,

I was on a long wikibreak. I started to work again on most-perfect magic square, see sandbox/squares, sandbox/squares (details), Values of the Chautisa Yantra_magic square and commons:project:Featured_picture_candidates/File:2152085cab.png.
The informations are to large for a Wikipedia article. Please ket me know at user talk:Gangleri if somebody can cooperate in writing, proofreading, advising about these topics.

links at The On-Line Encyclopedia of Integer Sequences!

search "magic+square"

"most perfect magic square"

A151941 The number of most-perfect magic squares of order 2^m where m>=2.

searching the "all ones" sequences

I have some ideas about making a generalisation of the Frénicle standard form using Galois group (see Galois theory) and residuals (see Isomorphism, Automorphism) to show that there is only one "generalised esentialy different" most-perfect magic square

examples ilustrates some of the homeomorphisms

Best regards and greatings from Munich. Best regards
