Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 256

A minimal faithful permutation representation — 5 generators on 28 points:

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