Ungreps is a number equal to |1|1(76) ( or 211(76) ) using Revised Pehan Notation.[1] The term was coined by Licorneuhh.

It is also equal to |1|076(76) = |1|075(Greps ).


Notation Approximation
BEAF \(\{76,76,1,1,2\}\)
Hyperfactorial array notation 76![2,1,2]
Strong array notation s(76,2,1,1,2)
Fast-growing hierarchy \(f_{\omega^2+1}(76)\)
Hardy hierarchy \(H_{\omega^{\omega^2+1}}(76)\)
Slow-growing hierarchy (using this system of fundamental sequences) \(g_{\varphi(1,0,0,0)}(76)\)
