\((((\pi!)!)!)\), therefore would have approximately been:
\(\pi! = 7.18808272898\)
\(7.18808272898! = 7380.55555766 \)
\(7380.55555766! = OVERFLOW \)(at least for my 50G)

That’s a job for super-wp34s:

pi ! ! 1 + LNgamma 10 LN / IP RCL L FP 10^x —> 4.41316713166

x<>y —> 25345

=> ((pi!)!)! = 4.41316713166*10^25345


or, approximately, 490347/111110*10^25345

Notice that (pi!)! ~ 66425/9 is much nicer.

PS: LOGGAMMA on the HP 50g gives a less accurate mantissa: 4.4131694182
