Finding loop point of finite state machine:, elaborated here.
Classic 3 body calculation here as elaborated here and motivated here.
A simple explicit version of the same physics.
Tiling the hyperbolic plane.
Pretty good polynomial root finder

Code from testing generalizations of axial vectors
Here is an Algol 68 program motivated here (about free motion of rigid body),
Several programs associated with Motion of a Rigid Body
A numerical anomaly illustrated with this code.
Fast Fourier Transform.
Runga Kutta code.
linear equation solver and
eigen described here;
