Presentation

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

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

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