7-11 & the Hexagon

Here is a short list of Centered Hexagonal Numbers 1, 7, 19, 37, 61, 91, 127, 169, 217, 271, 331, 397, 469, 547, 631, 721, 817, 919

If you add each of these numbers up into single digits your list of numbers will like this 1,7,1,1,7,1,1,7,1,1,7,1,1,7,1,1,7,1

Which looks like 1 ... 7-11 ... 7-11 ... 7-11 ... off until forever so I suppose

you may see 17's

I got all hot and flustered and had to extrapolate on my diagram'in skillz
