visualisations of primes / cycle representations

A peaceful night for you,

this is a visualisation for the exponentation of 2*2 matrixs with determant 1 mod f.
I think it is mathematical correct, but perhaps there might be a more beautiful visualisation possible.

For mathematicians, who likes visualisations of prime pattern I suggest proudly my other implementations in php:

[URL]http://devalco.de/unit_circle/system_unit_circle.php[/URL]
[URL]http://devalco.de/unit_circle/system_tangens.php[/URL]

All my friends ask me daily, if there is a new Mp arrived.
Some friends asked me also, if the amound of Mp is not limited.
The problem is, if I try to explain them some Number theory, they shut down immediatly.
I am glad, that spring is arriving and removes some depressiv moods.

After removing some bugs and some duplicates it looks nicer:

The matrixs mod p, with p=3 mod 4 look o.k.

but the other matrixs mod p, with p=1 mod 4 contain elements which do not "lead" to the identity matrix:
For example: p:=37 (16, 23, 23, 33)^(36*38)=/=(1,0,0,1).

Why ? or is it a bug ?

There might be a more mathematically accurate title for this thread:
something like : visualisation of different fields mod p
Perhaps a mod could improve the title.

<snip>[/QUOTE]It's a bug. I note also that the determinant of your matrix isn't 1 (mod 37), but is rather Mod(24,37).
[code]? M=Mod(1,37)*[16,23;23,23]
%1 =
[Mod(16, 37) Mod(23, 37)]

[Mod(23, 37) Mod(23, 37)]

? M^(36*38)
%2 =
[Mod(1, 37) Mod(0, 37)]

[Mod(0, 37) Mod(1, 37)]
