Hi Nick,
Nice record wheel!
Just some info for other's interested in wheels.
Your 21-6-6-7 covers each of the 21 numbers 2448 times.
If you were to remove all lines containing the upper bound [21]
This would also create the record wheel 20-6-6-7 = 6120.
This method can be repeated to produce all of the records for smaller 6-6-7 wheels.
This method will only work for certain types of coverings.
Method easily achieved using covermaster to manipulate the numbers.
Producing 21-6-6-7 with Ininuga was not possible & would take time with CM.
Rgds,
SRM.
