Presentation

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

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

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