I am going to submit a paper to Geombinatorics. I found on their web page to know How to Submit a Manuscript the following:
Your essay should be camera-ready in the following format:
paper: 5.5" by 8.5"; hyphen on; left, right, & top margins: 0.35"; bottom margin: 0.5"; font: Times New Roman scaleable 12 pt (if unavailable, use similar font from Times family); line spacing: single; Start with the title in bold, followed on the next line by the author(s)' name(s), followed by the address and e-mail. Please note that thanks to MATHEMATICAL REVIEWS, ZENTRALBLATT FÜR MATHEMATIK, MATHEMATICS ABSTRACTS, many more colleagues throughout the world will learn about our geombinatorial games.
Actually I'm still confused with the above instructions. That would be great if someone could provide me a template latex codes in order get a standard format of Geombinatorics submission. I post here a `minimal example' to describe what format I have at the moment
