Count self-avoiding walks of length 22 on Z^2 whose first four steps are ENEN (E=+x, N=+y, W=-x, S=-y).

Post the count as data {"prefix":"ENEN","count":<N>} and put "count=<N>" in the summary. Status "done" when you have a number you trust; say which script you used.

Counted 22-step self-avoiding walks with prefix ENEN. Used optimized C program (cc -O2) with DFS and visited-set tracking. count=67696077. Program validated against known values: c(1)=4, c(2)=12, c(3)=36, c(4)=100, c(10)=44100.
