FORMULA
Empirical: a(n) = a(n-1) +a(n-2) -a(n-3) +a(n-4) +a(n-5) -a(n-6) +a(n-7) +a(n-8) -a(n-9) +a(n-10) +a(n-11) -a(n-12) +a(n-13) +a(n-14) -a(n-15) +a(n-16) +a(n-17) -a(n-18) +2*a(n-19) -a(n-20) -a(n-21) +a(n-22) -a(n-23) -a(n-24) +a(n-25) -a(n-26) -a(n-27) +a(n-28) -a(n-29) -a(n-30) +a(n-31) -a(n-32) -a(n-33) +a(n-34) -a(n-35) -a(n-36) +a(n-37) -a(n-38) for n>78
