 This page says:
 {{{
 generator |  approx. memory requirements
 kreutzer1986 | 1368*sizeof(uint32_t)
 }}}

 I checked this requirements.
 {{{
 #include <iostream>
 #include <boost/random/shuffle_order.hpp>

 int main()
 {
     typedef boost::random::kreutzer1986 dist_type;

     std::size_t size = sizeof(dist_type) / sizeof(dist_type::result_type);
     std::cout << size << std::endl; // 99
 }
 }}}

 {{{
 // <boost/random/shuffle_order.hpp>
 typedef shuffle_order_engine<
     linear_congruential_engine<uint32_t, 1366, 150889, 714025>,
     97> kreutzer1986;

 // shuffle_order table size 97 + linear_congruential_engine
 }}}

 If I understand correctly, `kreutzer1986` size shoule be
 `98*sizeof(uint32_t)`.
