A quotation for today

Peter Barlow (1776 - 1862)

2³⁰(2³¹-1) is the greatest perfect number that will ever be discovered, for, as they are merely curious without being useful, it is not likely that any person will attempt to find a number beyond it.

Quoted in D MacHale, Comic Sections (Dublin 1993)
