    The smallest number which can be expressed as the product of two consecutive prime numbers, and which produces a palindrome when multiplied by its reverse, as in: 2021 = 43 x 47 2021 x 1202 = 2429242 Hope that this mathematical property of 2021 is enough to drive Covid-19 away from the world.

      I have my doubts that viruses can count, much less do multiplication. Almost anything is worth trying, though! :-D

          Please ... a little detail on the process you used to find this, or what motivated you to find/compute this. curiously, Bill

            Sorry to disappoint you that I did not compute this. Just got it in a WhatsApp forward. Cross-checked the calculation and shared it here. My mistake that I did not attribute it to WhatsApp University. :-)

              The problem is that they are multiplying too quickly

                They can certainly multiply.
