• Numbers of the form 4k^4 or (kp)^p for prime p > 2 and k = 1, 2, 3, ....at n=30A097792
• Consider the sequence of circles C0, C1, C2, C3 ..., where C0 is a half-circle of radius 1. C1 is the largest circle that fits into C0 and has radius 1/2. C(n+1) is the largest circle that fits inside C0 but outside C(n), etc. Sequence gives the curvatures (reciprocals of the radii) of the circles.at n=7A099938
