theorem Th25:
  for L be lower-bounded with_infima antisymmetric RelStr for a be
  Element of L holds a"/\"Bottom L = Bottom L
proof
  let L be lower-bounded with_infima antisymmetric RelStr;
  let a be Element of L;
  Bottom L <= a "/\" Bottom L & a"/\"Bottom L <= Bottom L by YELLOW_0:23,44;
  hence thesis by YELLOW_0:def 3;
