Happy Saint Patrick's Day! I'm going to coin 5 Saint Patrick's Day food numbers every year!
Irish soda bread = 317 ->_{317} 317 in Peter Hurford's extension of chained arrows (Class 9: Quadratic omega level)
Irish stew = [317, 317, 317, 317] in Graham Array Notation (Class 8: Linear omega level)
Corned beef and cabbage = 317![1(317)2] in Hyperfactorial array notation (Class 18: Bachmann's collapsing level)
Paleo BBQ pork shepards pie = E317(#{&_2}#){(&_2)_1}#317 in Extended Collapsing-E Notation (Class 19: Higher computable level)
Shamrock shake = 317[317] in Copy notation (Class 2)
