# An English question for a logical term

Consider a tuple of logical expressions: $(P_1, \ldots, P_n)$ such that $P_i\Rightarrow P_{i+1}$ for every $i=1,\ldots,n-1$.

An English question: Should I call it implications tuple or tuple of implications?

• If you want to choose the shorter form, I suggest that "implication tuple" would be a bit more idiomatic, even though it may look peculiar to you. – John Hughes Jul 20 '14 at 17:57
