I'm on page 24 of 172 of The Higher Arithmetic by H. Davenport:

"It is not known whether there are any odd perfect numbers, nor is it known whether the series of even perfect numbers continues indefinitely. The first five even perfect numbers are

                                      6, 28, 496, 8,128, 33,550,336."

Hmm..., I wonder, whether 33,550,336 might be the largest number used by the Ancient Egyptians, as it were. That would be rather remarkable, indeed!

A lakh ( /ˈlæk/ LAK or /ˈlɑːk/ LAHK; also lac; abbreviated L; Sinhala: ලක්ෂය, Hindi: लाख, Marathi: लाख, Nepali: लाख, Bengali: লাখ, Urdu: لاکھ) is a unit in the South Asian numbering system equal to one hundred thousand (100,000; 105), written as 100,000. From Wikipedia, the free encyclopedia


Very curious, indeed....
