Acknowledgments
A book of this size and quality would not have been possible
without using the knowledge created during
centuries of mathematical research,
and without the help and support of lottery enthusiasts, fascinated
by the subject of creating and improving
lottery
coverings. Many thanks to Dragan Stojiljkovic and Francesco Santisi
for their permission to use some of their records in my book and also to
Heikki Hammalainen, Malcolm Greig and Katherine Heinrich, with whom I have
worked on covering problems at various stages
of my research. Special thanks to Riccardo Bertolo and Rade Belic who fall
in both of the above mentioned categories. In addition, I want to express
my gratitude to unknown number of other researchers and lottery enthusiasts
who have either contributed to the knowledge on coverings and the current
table
of records or have inspired the search for these beautiful objects.
