Presentation

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

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

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