If you make a video about a number bigger than 1,000,000 use the hashtag #MegaFavNumbers and we'll add it to the playlist!

Here is my current mega-favourite number:

1,169,809,367,327,212,570,704,813,632,106,852,886,389,036,911

This is the OEIS page for A249836: Numbers n for which tan(n) is greater than n.

Thanks very much to Jacob Vecht for emailing me their new interesting integer. Keep an eye out for when all their newly discovered numbers appear on the OEIS.

These are the ones I found:

tan(1) = 1.6

tan(11) = -226

tan(33) = -75.3

tan(52174) = -181570.3

tan(260515) = 383610.7

tan(573204) = -3402633.8

tan(37362253) = 37754853.4

tan(42781604) = -85369290.4

tan(122925461) = 326900723.5
