First a Quintic is the lowest order polynomial for which there is no known fomulatic solution. Chose Quintic as the name for my first Company, as there were five of us, and we were a disperate lot. Not surprisingly after 3.5 years there was a split. That instance of the Company was finally disolved in or around 2015.
In 2016 I started up another company called Quintic, just because I liked the name. its web site, (but not the company) is still active at www.quintic.co.uk. The compnay itself was closed down in 2019 – as I had retired
And, finally, if you search Google or, better still, DuckDuckGo for” Quintic Cambridge” you will not get any references to the 1995 Quintic company. Oh Yes!!!
