Presentation

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

A minimal faithful permutation representation — 6 generators on 28 points:

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