How to set up Vectorization properly?

I am trying to set up a list like as the example shown below. Basically it starts with 1 to 4, then jumps by 13, then proceeds another 4 then jumps by 13 again.

I understand I can do 1:13:end to get a simple 1,14,27 etc list by how would I go about doing this alternative list in vectorised format?

Thanks.

X = [1,2,3,4,17,18,19,20,33,34,35,36...]

>> reshape(bsxfun(@plus,(1:4).',0:16:16*3),1,[])
ans =
  1  2  3  4  17  18  19  20  33  34  35  36  49  50  51  52

MATLAB versions since R2016b:

>> reshape((1:4).'+(0:16:16*3),1,[])
ans =
  1  2  3  4  17  18  19  20  33  34  35  36  49  50  51  52
