Hi CCLrs,

It seems that the only commonly available basis set that 
employs a geometric progression of primitive exponents,
that is an even tempered or well tempered sequence, is the
well tempered basis set WTBS.  This basis is quite large! 
For He, it is [17s]->(1s).  

My questions is, are there other geometric basis sets 
available that are not so large?  

Cheers, Matt
