Presentation

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

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

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