Presentation

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

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

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