Possible Continuation:

Undecafactorial n!11

Duodecafactorial n!12

Triskadecafactorial n!13

Quadradecafactorial n!14

Quintadecafactorial n!15

Sexadecafactorial n!16

Septemdecafactorial n!17

Octadecafactorial n!18

Enneadecafactorial n!19

Vigintafactorial n!20

Trigintafactorial n!30

Quadrigintafactorial n!40

Quinquagintafactorial n!50

Sexagintafactorial n!60

Septuagintafactorial n!70

Octagintafactorial n!80

Nonagintafactorial n!90

Centifactorial n!100

Notation Strength:

n! is always less than nn so nn may be used as an upper bound. As your factorials increase in the form n!1, n!2, n!3, ... the expression a!m is bounded by (nn)n or nn 2.
