I am a retired Civil Engineer PE MD 10518 (64 yrs old) and have always studied mathematics both theoretical and applied. I use Excel and the Basic programming language. I have written a number of unpublished engineering papers on such topics as: Vehicle Moving Load Analysis, Structural Slab Design, various Load Analysis for Bridge Ratings.

My mathematical papers include:

• An Improved Prime Number Counter
• A Twin Prime Counter,
• Consecutive Prime Pairs,
• Decomposition of All Prime Pairs,
• Prime Place Numbers,
• and Most recently: Numbers Appearing in the Decimal Expansion of their Reciprocals.

The last one has revealed an integer sequence 3,6,7,14,17,28,59,83,86,87,89,97,118,... that may be of use to this website. I would be glad to provide my paper as background.
