Nature of problem:
The construction of models describing the four fundamental interactions in the framework of the field theory formalism is currently a central physical problem. The generally covariant multidimensional theories of the Kaluza-Klein type are rather promising in this respect. To construct and analyze the Lagrangians and the equations of motion in this theory, knowledge of the connection, curvature, Ricci tensor, etc., for the group quotient space G/H is required.

The available computer memory is the severest restriction.

Running time:
Strongly depends on the dimension of space and explicit form of metric and mix matrices.
