Fz- is a prefix used on a number n to indicate $$n^n$$ or equivalently $${^2}n$$ (i.e n tetrated to 2). It was invented by Allstair Cockburn to continue the gar- prefix invented by his son.[1] Fz(n) is equivalent to $$n[3]$$ (triangle(n)), using Steinhaus-Moser notation.

The first few values of fz-n are 1, 4, 27, 256, 3125, 46,656, 823,543, 16,777,216, 387,420,489, and 10,000,000,000.
