var ind = (v[0] & mask) + (v[1] & mask) << 5 + (v[2] & mask) << (5*2)
var result = compare_ind == ind

var v = [1, 2, 3]
var result = compare_pos[0] == v[0] && compare_pos[1] == v[1] && compare_pos[2] == v[2]

var v = [1, 2, 3]
var str = v[0] + '|' + v[1] + '|' + v[2]
var result = compare_str == str
