Presentation

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

A minimal faithful permutation representation — 3 generators on 28 points:

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