Table of n, a(n) for n=1..57.

EXAMPLE

If n=7, then (p(7)-2*7)=17-14=3=a(1).

If n=8, then (p(8)-2*8)=9-16=3=a(2).

If n=9, then (p(9)-2*9)=23-18=5=a(3).

If n=12, then (p(12)-2*12)=37-24=13=a(4).

If n=15, then (p(15)-2*15)=47-30=17=a(5).

If n=19, then (p(19)-2*19)=67-38=29=a(6).

If n=20, then (p(20)-2*20)=71-40=31=a(7), etc.
