- Field Detail
  - bits
```
public static int bits
```
    The number of bits of state of the generator.
  - twoToBitsMinus1
```
public static java.math.BigInteger twoToBitsMinus1
```
    The period of the generator (2^bits − 1).
  - factor
```
public static final java.math.BigInteger[] factor
```
    Factors of the Fermat “primes” up to the eleventh (2²⁰⁴⁸ + 1).
  - cofactor
```
public static final java.math.BigInteger[] cofactor
```
    An array of cofactors. Entry 0 ≤ i < numCofactors contains twoToBitsMinus1 divided by factor[i]. Note that some entries can be null if bits is less then 4096.
  - numCofactors
```
public static int numCofactors
```
    The actual number of valid entries in cofactor.
- Method Detail
  - mPow
```
public static void mPow(java.math.BigInteger e)
```
    Computes the power to a given exponent, given the quadratures.
    
    Parameters:
    
    e - an exponent smaller than or equal to 2^bits.
  - main
```
public static void main(java.lang.String[] arg)
