Solve #5 a,b, & c.

-tV3 = tn-tg (with tile ton R is an equivalence relation. 5. Let s, = { tit2 tn I t,e {0, 1, 2 } for i-1, 2, . . . ,n), ie. the set of ternary strings of length n. List (in full) the equivalence classes for each of the following equivalence relations on the given set. where a R b if and only if the digit 2 appears the same number of times in a as in b. b) On Sa, where a R bif and only if the digits in a are some permutation (which i including the option of having the same order) of the digits in b. c) On S3, where a R b if and only if the sum of the digits in a equals the sum of the digits in b
