Presentation

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

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

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