Presentation

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

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

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