I may be stating the obvious, but it looks like the numbers are
doubling per iteration
{. 0 {"1 ((+*:)^:8~)(12%~i:_12)j.~/18%~_36+i.44
4.41152e66j_1.05844e67
{. 0 {"1 ((+*:)^:9~)(12%~i:_12)j.~/18%~_36+i.44
_9.25685e133j_9.33868e133
{. 0 {"1 ((+*:)^:10~)(12%~i:_12)j.~/18%~_36+i.44
_1.52155e266j1.72894e268
It overflows at 11
I don't see how it could have worked with the same inputs above 10 before
