## The function is currently defined as
function (items, rules, itemDictionary, chain, del, start, element_range, 
    seqlen, number) 
{
    number = number
    rule <- generateRule(itemDictionary, chain, del)
    result <- sequence(start = start, rule = rule, seqlen = seqlen)[[1]]
    validation <- check(items, result, element_range)
    if (validation == 0) {
        if (number < 3) {
            number = number + 1
            val(items = items, rules = rules, itemDictionary = itemDictionary, 
                chain = chain, del = del, start = start, element_range = element_range,
