class_docstr: Represents ordinal exponential and multiplication terms one of the
  building blocks of the :class:`Ordinal` class.
  In ``OmegaPower(a, b)``, ``a`` represents exponent and ``b`` represents multiplicity.
code: def __new__(cls, a, b):
      if isinstance(b, int):
          b = Integer(b)
      if not isinstance(b, Integer) or b <= 0:
          raise TypeError("multiplicity must be a positive integer")
  
      if not isinstance(a, Ordinal):
          a = Ordinal.convert(a)
  
      return Basic.__new__(cls, a, b)

label_desc: Use image node_id 1 for calling the OmegaPower obj's underlying member method code with example usage: obj.__new__(cls, a, b) and returns: Basic
