 A179541 a(n) is the least possible smallest period attainable by the action of a periodic sequence of binary operations <+>,<-> (see A179382,A179480), beginning with 2n-1<+>1 or 2n-1<->1 0
 1, 1, 1, 1, 2, 2, 1, 1, 3, 2, 4 (list; graph; refs; listen; history; text; internal format)
 OFFSET 2,5 COMMENTS The minorizing sequence for all sequences of type A179382,A179480 with arbitrary periodic rotation of the binary operations <+>,<->. LINKS EXAMPLE Let n=12, 2n-1=23. Considering periodic sequence <+>,<->,<+>,<->,..., we have 23<+>1=3, 23<->3=5, 23<+>5=7, 23<->7=1, 23<+>1=3,... Thus a(12)<=4. It is not difficult to verify that a(12)>3. Thus a(12)=4. CROSSREFS Cf.
