COMMENTS
The sequence consists of the multiples of 8 that are greater than or equal to 64, together with 48. The result is due to D. Boyd, Berend, and Golan. It had been conjectured that the sequence began with 64, but Boyd discovered the set
{1,2,7,10,11,12,13,14,16,17,21,22,27,28,32,33,35,36,37,38,39,42,47,48},
which shows that 48 is 5-powerful.
