What is the easiest way to find the nearest power of 2 + 3 in Pd for tabosc4~ to work correctly?

Basically, what I'm doing is as follows:
Copying one table multiple times into a larger table so that I get X copies in the larger table (the reason I'm doing this is so I can modify each copy slightly, say in amplitude, or even use a different table at that position).

I correctly resize the larger table so that it can hold X copies of the smaller table, but I need to be able to use tabosc4~ on this larger table, so what I really need is a patch that can compute the larger table's pow2 +3 size.

Yop,

sorry if I misunderstood, but if you want to use tabosc4~ to read your "big" table this seems a bit nonsense, imho, as at boundaries between the "copies" you mentionned the audio would be discontinuous (if you see what I mean). So even if you put three more points at the start and the end of the "big" file you'll lack such additionnal points within this very table.
