I'm very impressed with the 925 classification. Where do you come up with it?

921 = sigma 10^(x-1)*x^(x-1) for x = 1 to 3

This is 1 + 10*2 + 100*9. Cute, but did you have this at your fingertips? Have a recognition for the partial sums?

Wikipedia gives you that it is pentagonal and centred square. I examined those that are both 1, 5 , 145, 925. To make 925 differ composite gets rid of 1 and 5 and semi prime gets rid of 145. Nothing particularly clever!

Just looked at 9 2 1 as a sequence and see what I could come up with. Thought it looked quite pretty.
