If we want to set-up a typical inductive proof, we can consider the binary predicate P ( n, k) := k n ≥ n and apply induction on k : (i) Basis : k = 2. We have that 2 n = n + n ≥ n. (ii) Induction step : assume that the property holds for k ≥ 2 and prove for k + 1. bishop\u0027s stortford model railway club

WebLogicians have a slang for this; they call it the “arity” of the predicate. This odd word comes from taking the “ary” on words like “binary” and “trinary”, and making it into a noun.
