Minimal Defining Sets of the 2-(11,5,2) Designs – D1

=======================================================================

Design parameters are 2-(11,5,2), b=11

Blocks of the design are:
01237 01456 02589 0368a 0479a 1248a 1359a 16789 23469 2567a 34578
The design is simple

=======================================================================

Auto’m group order is 660

All non-isomorphic minimal defining sets are:

01237 01456 02589 0368a 1248a
Size=5 |Aut|=2
01456 02589 0368a 1248a 1359a
Size=5 |Aut|=10

=======================================================================

Size Count
