224 is a practical number, and a sum of two positive cubes 2 + 6.

224 is the smallest k with λ(k) = 24, where λ(k) is the Carmichael function.

The mathematician and philosopher Alex Bellos suggested in 2014 that a candidate for the lowest uninteresting number would be 224 because it was, at the time, "the lowest number not to have its own page on Misplaced Pages". As of July 2014, 224 has its own Misplaced Pages page.
