Interesting bitstrings

Here's the 5-bit version:

00001
00010
00100
01000
10000

11110
11101
11011
10111
01111

00001
00011
00111
01111
11111

11110
11100
11000
10000
00000

So it looks like about 4*n for n bits. So approximately 512 for 128-bit (AES). The related-key related-ciphertext related-plaintext challenge will have 2*512*512=500,000 lines. (The factor of 2 for encrypt/decrypt).
