### OEIS A110492

Some Divisibility Properties of Sums of Prime
Numbers

### OEIS A038554

Graph of sequence A38554 of the Encyclopedia of Integer Sequences:
n (horizontal) varies from 1 to 512; a(n) (vertical) varies from 1 to 256

Note the fractal-like nature of the graph.

### OEIS A048647

Graph of {a(n)}, where a(n) is obtained by writing n in base 4, then replacing
each digit by its negative (base 4).

n and a(n) both range 1-1024. This
is sequence A48647 in the On-Line Encyclopedia of Integer Sequences.
