because the highest value is 172 i'd like to some how generate a set of numbers like the following:

0,30,60,90,120,150,180

public enum enum1{   f1=0,   f2=1,   f3=2,   f4=3}

private enum1 myEnum1;

public enum1 MyEnum1
{
  get ( return myEnum1; }
  set 
  {
    if (value == f1 || value == f3)
      myEnum1 = value;
    else
      throw new ArgumentException("Invalid assignment");
  }
}

public enum enum1{   f2=1,   f4=3}
public enum enum2{   f1=0,   f3=2}
