I've stumbled across what appears to be character clustering in P2SH Base58 addresses that I can't find documented anywhere. I'm calling them "compression basins." Ten specific characters (N, R, S, T, U, Y, b, e, g, m) exhibit higher co-occurrence rates than the other 48 Base58 characters when searching P2SH prefixes with vanitysearch. Using -c 3*turn*me*beg* on a 4090, I hit 3FtURnMeBegsZLGKQrxggR9BoZxmGNKMyR in 10-20 minutes, that's 12 basin characters forming 4 readable words. The natural clustering (including the unintended 's' in "begs" and "my") suggests this maybe isn't just luck.
Theory: This appears to be a probabilistic advantage through Hash160 & Base58 encoding properties. Substring searches using these basin characters are noticeably more likely to converge. Challenge: Beat 12 characters / 4 words (intentional or not). First person posts proof here gets $5 BTC.
Case insensitive accepted Wildcards allowed Must use basin character subset N, R, S, T, U, Y, b, e, g, m
Has anyone encountered research on non-uniform character distribution in Base58 post-Hash160?
*Checking into it deeper, I do believe these may be resulting clusters from searching the 31h1 to 3R2c range?
