Numbers which can not be expressed as the sum of distinct triangular numbers.

[Tanya Khovanova]

I've found two sequences of those:

A066614  	 	 Numbers which can not be expressed as the sum of distinct triangular numbers.  	 	

	2, 5, 8, 12, 20, 23, 33 

and

A053614  	 	 Numbers that are not the sum of triangular numbers.  	 	

	2, 5, 8, 12, 23, 33

BTW 20 = 1+3+6+10.
