Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 128

A minimal faithful permutation representation — 4 generators on 28 points:

(2,4)(5,6,8,11,9,7,10,12)(14,19,22,21)(15,23,24,25);(1,2,3,4)(5,7,8,12,9,6,10,11)(13,14,16,19,18,22,17,21)(15,20,23,26,24,28,25,27);(13,15)(14,20)(16,23)(17,25)(18,24)(19,26)(21,27)(22,28);(13,16,18,17)(14,21,22,19)(15,23,24,25)(20,27,28,26)
