I have a set with 26 special domino stones. Every stone carries a lower case Latin alphabet letter and an upper case Latin alphabet letter:
a b c d e f g h i j k l m n o p q r s t u v w x y z F M C Z P A Q T S K J U B Y O E G W I H L X R V N D
I know an English word of ten (not necessarily distinct) letters that I can spell with these stones on the table. If I arrange ten domino stones from left to right so that their lower case letters spell my word, then the upper case letters also spell my word but backwards. What is this word?
