Nand
(Built-in Mathematica Symbol) Nand[e_1, e_2, ...] is the logical NAND function. It evaluates its arguments in order, giving True immediately if any of them are False, and False if they are all True.
Nor
(Built-in Mathematica Symbol) Nor[e_1, e_2, ...] is the logical NOR function. It evaluates its arguments in order, giving False immediately if any of them are True, and True if they are all False.
OwenT
(Built-in Mathematica Symbol) OwenT[x, a] gives Owen's T function T(x, a).
