## hyperfactorialA number such as 108, which is equal to 3 ^{3} × 2^{2} ×
1^{1}. In general, the n-th hyperfactorial H(n)
is given byH(n) = n^{n} (n-1)^{n-1}
... 3^{3} 2^{2} 1^{1}
The first eight hyperfactorials are 1, 4, 108, 27648, 86400000, 4031078400000, 3319766398771200000, and 55696437941726556979200000. ## Related entries• large numbers• superfactorials ## Related category• TYPES OF NUMBERS | |||||
