Comm. NT: 1.
Sammasanañāṇakathāvaṇṇanā

Comprehension by placing together in groups (totals) the states that are differentiated into past, future and present is ‘comprehension by groups.’ This, it seems, is the term used by the inhabitants of Jambudīpa (India).
However, insight into states by means of the method beginning, ‘Any materiality whatever’ (M III 16) is ‘inductive insight.’ This, it seems, is the term used by the inhabitants of Tambapaṇṇidīpa (Sri Lanka).
That is why he said “to inductive insight called comprehension by groups’
