Appears in sequences

• a(n) = n^4+4 = (n^2-2*n+2)*(n^2+2*n+2) = ((n-1)^2+1)*((n+1)^2+1).at n=30A057781
• a(n) = a(n-1)^n + n; a(1)=1.at n=3A155731
• a(n) = 16*n^4 + 4.at n=15A222655
• Continued fraction that converts to its own decimal expansion; the sequence becomes strictly increasing when all zero terms are removed.at n=13A391761
