Math::NumSeq::TotientCumulative -- cumulative totients
use Math::NumSeq::TotientCumulative; my $seq = Math::NumSeq::TotientCumulative->new; my ($i, $value) = $seq->next;
The cumulative sum totient(1) to totient(i).
See "FUNCTIONS" in Math::NumSeq for behaviour common to all sequence classes.
$seq = Math::NumSeq::TotientCumulative->new ()
Create and return a new sequence object.
$value = $seq->ith($i)
$bool = $seq->pred($value)
Return true if
$value occurs in the sequence, ie. is a sum totient(1) to totient(i) for some i.
