FORMULA

Generalized nim sum m + n in base q: write m and n in base q and add mod q with no carries, e.g. 5 + 8 in base 3 = "21" + "22" = "10" = 1.

a(n) = 2*(n-a(floor(n/2))). a(n) = 2*A063694(n). - Vladeta Jovovic (vladeta(AT)eunet.rs), Feb 23 2003

Equals A088442 - 1. - Chris Groer (cgroer(AT)math.uga.edu), Nov 10, 2003
