%N Successive integers produced by Conway's PRIMEGAME, starting with 12 rather than 2.

%C After 240 steps, this sequence reaches 32 = 2^5.

%e Multiply 12 by 15/2 to obtain 90. Then for 90, we can multiply 90 by 15/2 also to obtain 675.

%t (* First run the program for A203907 to define conwayProc *) NestList[conwayProc, 12, 50]
