Presentation

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

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

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