It is my intention that with these files you can get almost every information you wish about regular polytopes upto the 5th dimension. Much information is derived from:
H. S. M. Coxeter

Methuen & Co. Ltd., London, 1948
for which a Dover reprint does exist. I have made an attempt to find all regular objects found in the regular polytopes (and in this found a few compounds not given by Coxeter, see, amongst others, section 18 of {5, 3, 3}).

The information is organised as follows:

New information about compounds:

The information here is still incomplete and in progress!
