Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 128

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

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