Mathworld states that:

"Returning to Pegg's definition of evil, the fact that pi is evil was noted by Keith, while I. Honig (pers. comm., May 9, 2004) noted that the golden ratio phi is also evil. The following table gives a list of some common evil numbers (Pegg and Lomont)"

Therefore **odious numbers **are the exact opposite of **evil numbers.**
