Made some smalls changes and now it takes care of the 2nd case of “Simple periodic sequence” as function **periodicIntSeqRepeatedNTimes(n, lo, hi)**:

```auto
int[] seq4_1_20, seqNeg4_1_20, seq1_10_Neg10;

void setup() {
  seq4_1_20 = periodicIntSeqRepeatedNTimes(4, 20);
  seqNeg4_1_20 = periodicIntSeqRepeatedNTimes(4, -20);
  seq1_10_Neg10 = periodicIntSeqRepeatedNTimes(-1, 10, -10);

  println(str(seq4_1_20));
  println();
  println(str(seqNeg4_1_20));
  println();
  println(str(seq1_10_Neg10));

  exit();
}

static final int[] periodicIntSeqRepeatedNTimes(final int n, final int hi) {
  return periodicIntSeqRepeatedNTimes(n, hi >= 0 ? 1 : -1, hi);
}

static final int[] periodicIntSeqRepeatedNTimes(
  final int n, final int lo, final int hi)
{
  final int
    qty = Math.abs(hi - lo) + 1, 
    len = Math.abs(n) * qty, 
    dir = hi >= lo ? 1 : -1, 
    seq[] = new int[len];

  for (int i = 0; i < len; ++i) seq[i] = i % qty * dir + lo;

  return seq;
}

```
